SS Amp Performance Characteristics

[Atmasphere]

That's fine. I'm not pushing.
I see things opposit. Just because I hear something does not mean I can't find it in my system. Most systems leave a lot in the box. The owners don't know how to get it out. Hearing what your missing is about finding what you have.

I put my new horn sub in. OMG. I found all the bass I was missing. Buying a SS amp would be a backward step. I had 2 very fine SS amps and my current amp slaughtered them. I'm so happy I was coached in a good direction.

One thing we heard over and over again is how different and better the bass was in our OTLs as opposed to whatever brand was being used, assuming the speaker was a good load for both amps.

My speakers are flat to 20Hz. Most tube amps with output transformers get in trouble in the bottom octave (which is why you want to use the preamp output for your subs if you can). Its nice to hear what that's about.

Most solid state amps have enough feedback that doing bass frequencies really isn't a problem. In older designs especially, this may not be true at higher frequencies where their distortion rises but for bass they are OK. The bigger issue is whether an amp used for subwoofer service has a big enough power supply and thermal capacity to run subs properly.

Dayton Audio has a subwoofer amp that is designed for lower frequencies and has its crossover built in. Its the one that Duke of Audiokinesis recommends for use with his Swarm subs. Its not expensive and does the job.

What is your crossover frequency from the horn sub to everything else?

I am still feeling it out. But I fluctuate between 62 and 84 hertz. I also swirch between 12 and 24 on the slope. I'm amazed at how audible the slope is. Phase is 0.
